Operation
The electric motor (4) is actuated by the automated manual transmission control module (N15/6) and starts to drive a gear pump (4a) to which it is connected by a coupling.

The rotary movement of the gear pump (4a) draws in the hydraulic fluid via the intake connection (4b). The hydraulic fluid is compressed and supplied to the hydraulic control unit via the pressure line connection (4c). The SEQ hydraulic pump (M46) also supplies the pressure reservoir with system pressure.
